Solution 2

you need to do like this

XML

<asp:TemplateField ShowHeader="False">
             <ItemTemplate>
                  <asp:ImageButton ID="Button1" runat="server" CausesValidation="False" ImageUrl="~/script/delete.gif" CommandArgument='<%# eval("MyRowId") %>' CommandName="Select"
                       AlternateText="Delete"></asp:ImageButton>
             </ItemTemplate>
        </asp:TemplateField>

C#

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        string name = e.CommandName;
        if(name=="delete")
           {
               //delete code 
           }
         GridView1.DataBind();
    }

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

how to get rid of this?
